The Lowdown

Hey guys, Rusty here. Let’s break down what the ocean’s got cookin' for us at Jaconé over the next couple of weeks.

Right off the bat, the first few days are a write-off with small, choppy slop. Don’t even bother waxing up just yet. The good news is that there's some real firepower on the horizon.

The first real standout for the experienced crew is Monday the 7th of September. A solid 8ft south swell hits, and the wind goes completely dead – glassy conditions morning and afternoon. The wave energy is pumping (1148), and it's got a good 10-second period. This is a proper groundswell, but the size means it’s for experts only. This break is consistent, so you’ll get waves, but expect a crowd because it’s going to be that good.

Right after that, Tuesday the 8th keeps the action rolling. The swell drops to a still-chunky 5ft from the south, and we get a moderate offshore breeze from the ENE. This is going to clean up the waves beautifully. The energy is still strong (616), making it a fantastic morning for intermediate to advanced surfers. This is your second best bet if you want something a little more manageable than Monday.

The middle of the week gets a bit average. Wednesday the 9th has a smaller, short-period swell (7 seconds, 6ft) that just doesn't have the grunt. Things then go quiet and inconsistent until the following week.

Now, looking way out to Monday the 14th, the models are showing a massive pulse of energy (3355). We’re talking a 10ft south swell with a long 13-second period. The wind would be offshore and clean – a perfect recipe. But here’s the kicker: the swell is forecast to be way too big for this break. It’s a real shame because the conditions would be epic. For paddle surfing, it's a no-go, but this is where the kite and windsurf crew are going to have a field day.

After that big pulse settles, Tuesday the 15th comes back into a good zone. A 6ft SSE swell with a solid 12-second period, groomed by a gentle offshore NE breeze. This is another quality session for experienced surfers, with strong energy (1019) offering some proper, clean waves.

The last few days fade out again. The 16th has a glassy 4ft SSE swell, but it's on the smaller side. The final days get messy and tiny, so don't hold your breath.

Water temp is about 73°F, which is normal for this time of year. The two standout sessions are Monday the 7th for that glassy, powerful wall of water, and Tuesday the 8th for a cleaner, slightly smaller but still excellent session.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
